pling embodying the principles of this invenllOn;

Fig. 2 a plan view thereof;

Fig. 3 a side elevational view thereof;

Fig. 4 a bottom view;

Fig. 5 a bottom view of a muffle portion of the nozzle; and

Fig. 6 a modified form of the mufiler.

The figures of the drawing are substantially double size to more cleariy illustrate the structure.

Numeral t designates a hose coupling having the conventional serrated portion 2 for engagement with a flei/:ible hose end 3, the coup'iing having a threaded portion l' for attachment with an outlet vaive of a Water supply system. Coupling i is provided With a lateral extension 5 having a threaded portion f: for receiving a tting i which may be termed a bonnet and is provided With an internal thread for interaction With the thread ii of the lateral extension 5. The bonnet is provided with a pacling or seat 8 adapted to abut the end 9 of the lateral eX- tension 5 to seal oif the flow passage of the extension. The bonnet ii is provided with an orifice plate 9 having small openings lll to provide a restricted flow of water. The plate 9 may be of rectangular form as shown in Figs. 4 and 5, and is attached to the bonnet 'i by screws il. A packing [2 is disposed between the mufe and the bonnet to secure a Water tight joint. In the modification shown in Figure 6, the mufle consists of a perforated screw plug E3 having openings Mi and slot 5 for purposes of inserting a screw-driver to screw the mufiie into its threaded seat.

50 In the operation of the device, the hosecoupling is connected in the Usual manner to the flexible hose, this connection being a conventional form and is further attached on the screw thread of a 'water supply outlet by its threaded portion ll. In odinary use, the bonnet 'i is screwed on thread 3 to abut the packing d against the end face 3 of the lateral extension 5, thus preventing any flow through the lateral passage. When desired, bonnet 'i may be unscrewed to cause the admission of fine streams of water from the Openings H3 of the plate 9 which may be useful to fill a container when 10 the hose system is otherwise in use for sprinkling purposes, or the small jets of Water may be utilized to cleanse the operatoris hands after the sprinkler has been moved or set up or if the hose has been weund on its reel, without break- 15 ing the connection of the hose coupling With the source of supply.

A device of the kind herein described provides instant use of water for washing purposes without interrupting the normal use of the hose or Without necessitating the unreeling of the hose from its support. The structure is of simple form and may be economically produced thus facilitating a wide use of the device.

Although one embodiment of the invention is herein. illustrated and described, it Will be obvious to those skilled in the art that various modications may be made in the details of construction without departing from the principles herein set forth.

I claim: A

1. A hose coupling comprising a Sleeve for receiving the end of a hose having a screW thread portion for engagement with a threaded outlet of a water supply line, said Sleeve having a 35 lateral extension provided with a thread for receiving a bonnet, said bonnet having a perforated orice plate at right angles to said lateral extension for restricting the fiow through the lateral extension.

2. A hose ooupling having a hose receiving end and a threaded portion for engagement With a source of water supply and having a lateral eX- tension for the flow of fiuid, said extension being provided with a threaded bonnet having a packing for sealing the lateral extension, and said bonnet having an orifice plate for limiting the flow through said extension, said orifice plate having perforations for restricted flow of Water at right angles to the flow through the lateral extension.
